Test your coding knowledge.
Three short exams to check what you know. Solve the crossword, spin the wheel and answer a question from the topic it lands on, or flip cards to match terms with their definitions.
Crossword Challenge
Fill in the coding terms. Most correct words in the least time wins.
How to play Read this first. The timer starts only when you press Start quiz.
Fill in the crossword with the right words. Each clue gives the number of a word and whether it goes Across (left to right) or Down (top to bottom).
How to play
- Click a white square in the grid, or click a clue in the Across or Down list. The current clue is shown above the grid and its squares are highlighted.
- Type the letters. The cursor moves to the next square by itself.
- To switch between Across and Down where two words cross, click the same square twice.
- Use the arrow keys to move around the grid and Backspace to delete a letter.
- The Filled counter shows how many words you have completed. Your letters are saved as you type.
- Clear grid removes all your letters if you want to start again.
- When you're done, press Submit answers.
Rules
- Fill in your details below and press Start quiz. The timer starts only then.
- Up to 3 attempts. Use the same name, mobile number and email each time. Only your best attempt counts.
- Once started, the timer never pauses. If you leave the page, the clock keeps running.
- Your progress is saved. Refresh or come back on the same device and browser to continue.
- When time runs out, your answers are submitted automatically.
After you submit
- Your score and time are shown.
- The grid shows which letters were right. Wrong or missing words are filled in red so you can learn them.

Spin the Wheel
Spin to pick a topic, then answer a question from it. Most correct in the least time wins.
How to play Read this first. The timer starts only when you press Start quiz.
Spin the wheel to pick a topic, then answer a multiple-choice question from that topic. Each spin is one round.
How to play
- Press the SPIN button in the middle of the wheel.
- The wheel turns and stops on a topic. A question from that topic appears with four options, A to D.
- Click the answer you think is right. You can't change it after clicking, so read all four options first.
- You see at once whether you were right (Correct!) or not (Not quite.), with a short explanation.
- Press Spin for round 2 (and so on) to go to the next round. The Round and Score counters at the top keep track.
- After the last round, press Finish & see results.
Rules
- Fill in your details below and press Start quiz. The timer starts only then.
- Up to 3 attempts. Use the same name, mobile number and email each time. Only your best attempt counts.
- Once started, the timer never pauses. If you leave the page, the clock keeps running.
- Your progress is saved. Refresh or come back on the same device and browser to continue.
- When time runs out, your answers are submitted automatically.
After you finish
- Your score and time are shown.
- A review lists every question with your answer and, if you got it wrong, the correct answer.
Tip: The 5 minutes are for all rounds together, and the wheel takes a few seconds to spin. Don't spend too long on one question.

Memory Flip
Flip two cards at a time to match each term with its definition. All pairs, fewest flips and least time wins.
How to play Read this first. The timer starts only when you press Start quiz.
8 cards lie face down: 4 show a term and 4 show its definition. Turn them over two at a time to find each term and its matching definition.
How to play
- Tap or click any card to turn it over. Each card is labelled Term or Definition.
- Turn over a second card to find its partner.
- Match: if the term and definition belong together, both cards stay face up and turn green.
- Not a pair: both cards turn red briefly, then flip face down again. Try to remember where they were.
- Keep going until all pairs are found. The bar above the cards shows the time left, your flips and the pairs found.
Rules
- Fill in your details below and press Start quiz. The timer starts only then.
- Up to 3 attempts. Use the same name, mobile number and email each time. Only your best attempt counts.
- Once started, the timer never pauses. If you leave the page, the clock keeps running.
- Your progress is saved. Refresh or come back on the same device and browser to continue.
- When time runs out, your answers are submitted automatically.
When the game ends
- The game ends when you find all the pairs, or when the time runs out. Pairs found by then still count.
- Every card you turn over counts as one flip, so a perfect game takes 8 flips.
Tip: Turn over unknown cards first and remember what you've seen. Guessing at random adds flips, and fewer flips can win a tie.
